"Grand Designs" celebrates 100 episodes in this its 10th series. Designer and writer Kevin McCloud follows the structural, financial and emotional voyage of ambitious couples as they bravely embark on the adventure of a lifetime - building their own homes. After 100 episodes and 100 individual projects, these extreme homemakers are still risking it all to experiment with technology, architecture and their own lifestyles. There are volatile neighbours, tight budgets, romantic restorations, the rotting corpses of 2000 pigeons, and of course, the ubiquitous battle with the elements; yet presenter Kevin is there through it all, to offer words of encouragement and wisdom, and to raise the occasional eyebrow... This series features 8 unique and extraordinary builds including a 99ft water tower, a minimalist glass box and the world s first computer cut home.
